Inaugurated by the Dutch charity KoZon, this program has shown remarkable success. As a result of the extremely dry conditions, most of the forests of Darfur are depleted, rendering firewood extremely scarce. When a camp of 20,000 refugees is placed in an area which normally supports a few thousand, locals fiercely defend their depleted firewood - to the point of raping the women and children who leave the camps to gather it. Through the use of solar cookers, which use only sunlight for cooking, trips outside the camps have declined 86%, demonstrably reducing the incidence of rape. The Solar Cooker Project has recently been picked up by the Office of the UN High Commissioner for Refugees (UNHCR) for use in four additional camps.
